Abstract
A polymer production method whereby: a flow reactor comprising a flow path wherein a plurality of liquids can be mixed is used; and a monomer is anionically polymerized in the presence of an initiator. The flow reactor comprises a mixer for mixing two liquids, said mixer comprising either a joint member having a double pipe therein or a static mixer member.
